To all whom it may concern:

Be it knownthat I, HENRY M. Loommn'a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, haveinvented certain Improvements' in Machines for Operating Upon the Heels of Boots and Shoes, of which the following description, in vconnection-With the accompanying drawings, isa specification, like reference characters on the: drawings indicating like parts in the several figures. o

This invention relates to heel breasting machines and is herein shown and described; as: applied, by Way ofexample, to a machine designed to operate. upon "heels which are to have a breast face of double curvature, such as are known in the art as orthopedic or anatomic fheels. It has been customary to breast heels of this sort upon the ordinary heel breasting machine by merely substituting a knife having a double curvature for the ordinary straight knife, or knife of single curvature, and sub;

stituting for the ordinary presser plate another having an end portion shaped to correspond to the knife of"double curvature. It is found in practice, howe'venthat in or der properly to I locate, thex'l'ong itudinal median line of the heel Withrespectto'the central portion of a knife offdoub'le curvature, in treating different heels,. it is nee-4 cssary to move the shoe laterally. Moreover, it is necessary, in orderto effect a change of contour of the heel vbreast, to change the knife to. one of; different curva-J,

ture. It is also .foundrthatthe: presser plate could not be accurately adjusted to the con tour of the knife in'prionmachines, because in such machinesprovision ismadefor ad-j just-mg the presser plate only longitudinally of a heel, which movement alone: fails to bring the front end of the plate intocorrespondence or parallelism With {the double curved contour'of the: knife. Etahas also been found necessary in prior machines, in order to breast properl -y shoes ofditterent sizes, to change} knives to correspond with the size of shoe being ,treated,-the.knife used on the smaller shoe having similar shape to that usedon the larger shoe but made. upon a reduced sm le.- It is' an obj ectotthe; invention-g therefore, to provide means; for; adjtistingrae shes lateiv ally relatively to the knife, so that a change m'contour of the heel may be efiected Wltlk out change of knives, and, a further object lJmTED Smite PATENT G ms of the invention is to provide means \Vh61'8- bythe forepa'rts of different shoes may be swung. predetermineddistances in opposite directions whereby a further change of contour of the heel breast may be effected with out "change of knives.

It is also an object of the invention to provide means for effecting proper adjustment of th'e edge of the presser plate into parallelism with the contour of the rear side 0f the knife. K

' is a further object of" my invention to provide means whereby heels of Widely varying sizes may be given breasts of substantiallyuniform appearance by the use of the same knife. V

Anfi important feature of the invention comprises a Work support upon which the shoe is held duringthebreasting operation which isprovided with means for efiecting its adjustment transversely of its line of movement for bringing a shoe into and out oflposition forithe breasting operation. The work support ispivoted atlits' lower end and the means which provides this pivotal move-' ment is mounted for sliding adjustment I uponwits trunnion, means being provided fonclamping the support in any, position of lateral adjustment While yet permitting. itsv pivotalmovement into and-out of operative position. This lateral adjustment enables the heel to; be positionedwith its median line at various points along theuknife edge," so that with a double curved knifeconsiderably wider than the usual heel'the median line of the-heel may be broughti-nt'ov different posite obliqueangular-"relationsto the plane of the breasting knife by adjustment of the 'movement of the member and thus equally and oppositely limiting the movement of the forepart engaging means into these angular relations This featur'ecis, of course, applicable to breastmg rights and lefts with straight or. single curvedknives and when used with "an ogee knife provides for still further varying the contours of the heel breasts without necessitating change of knives, by givingthe support for the toe portion of the shoe'a predetermined amount of movement equally in ,either'dlrection to vary therelation of the heel to the knife.

The lateral movement of the toe support,

- together with a. slightrmovement of the heel in the direction of its longitudinalme-j dian line, moreover, "furnishes means for breasting widely varying sizes of heels so that the appearance'oftheir breasts s practically identical.

,Another feature of the invention consists in a work support having a' lateral adjustment in combination with a toe rest having a transverse swinging movement whereby a still further increase in the number of variations in contour may be effected by varying the position of the heel relatively to a single knife of double curvature. V r

Another important feature of the invention comprises a presser plate which preferablyis moved downwardly to bring it into contact with the heel of the shoe and clamp the same upon the work support and which is mounted for lateral, as well as longitudinal, adjustment so'that all portions of the curve of its front :edge may be adjusted to V substantially the same distance from the back side of theknife. Since the knife and the front'edge of the presser plate'have a 7 double or ogee curvature, the usual adjust ment' provided for'the presser plate in a line perpendicular to the plane of a straight knife or to the general planeof a double curved knife is insufficient to bring all por- .tions of the curvev of the Dresser plate into I the plate against movement laterally holdsit from movement longitudinally. Hence, by

manipulation of a single means, adjustment in both directions may be efiected-simulta-' neously.

Another feature of my invention com prises means for holdingthe presser plate which contacts with the work so that it may be readily-detached. Means is provided for preventing longitudinal movement of the the same clamping means.

longitudinal movement of the presser, plate,

andboth the transverse and the longitudinal .movements of the presser plate maybe effected at the same time and both the plate and its support may beheld in position by By further loosening the same clamping means, further:

more, the plate may be removed, reversed being. necessary for breasting right and left orthopedic heels. v v 1 7 These and other features of the invention will appearniore fully from the following detailed description in connection with the accompanying drawings, and will be pointed out in the appended claims.

In the drawings V Figure 1 is a front elevation of-the improved breasting machineyFig. 2 is a sectionaldetail, illustrating the mechanism for effecting the lateral adjustment of the shoe support; Fig. 3' is a perspective view, partly in section, of the mechanism for effecting the adjustment of the lateral swinging .HIOIVQ- ment of the toe rest, Fig. 4: isa perspective viewiof'the p'resser plate and its supporting clamping means, taken'from a position below the same; F igs. 5, 6 and 7 are diagram matic views showing the relation of various heels to the knife. i

In Fig.1 the reference character 2 indicates the frame of. a power heel breasting machine of the usualtype, power being con tinuously applied to the pulley wheel f from which itis transmittedto the breasting V knife through suitable mechanism involving a one-revolution clutch which is arranged to be tripped by the treadle 6. Prior to the action of the treadle in tripping the clutch,

however, it acts through the rod 8, the spring 10, the lever 12 and the vertically movable slide 14 to depress the presser plate 6 upon the heel of the shoe to clamp the" shoe upon the shoe support in position to=be breasted.

' Uponthe-tripping of the clutch by further movement of the treadle the .knife-50 Iisactuated to breast the heel, the stop-60 descending with the knife and contacting with the shank of the shoe when'the knife has passed through the material of the heel.

Upon contact of the stop 60 with the shank nism, 1 thereby arresting its cutting action and preventing the knife from cutting into the shank. The mechanism thus far described is ofthe usual type and. forms no 2, for swinging movement upona stub shaft Y 21. Between the stub shaft 21 and the post is interposed a collar 22 carrying a flange 23 which has frictional engagement at 24- with a surface formed on the machine frame. To prevent endwise movement of the collar 22 and its flange23 relatively. to the stub shaft 21, a setscrevv25 is threaded into .th end of the stub shaft 21 and carries a washer 26 which bears upon the end of the collar'22. At the opposite end thestub shaft carries a resilient friction plate 29 which istiXed from rotation thereon by means of pins and a screw, as indicated in F The friction plate bears against a surface 31 on the chine frame and the collar is thus held from free rotation by the frictional contact between the surface 2 ion the machine frame and the flange 23, which contact is maintained by the action of the resilient plate 29 in forcing the stub shaft 21 and collar 22 with its flange 23 toward the right. The post 20 is clamped to the collar 22 by means of a bolt 27 which passes through the post 20 and is provided with a notch overlying the cylindrical surface of the collar 22. v The bolt 27 is actuated longitudinally by a hand nut 28, Fig. 1. It will now be seen that when the bolt 27 is freed bv loosening the nut 28, the post 20 may be slid longitudinally of the collar 22 to adjust the'worlr support transversely of the machine and to bring the longitudinal median line of the heel of the shoe upon the support to various positions along the edge of the knife 50. "When the handnut 28 is tightened, however, the bolt 27 is moved longitudinally and by reason of the notch therein is clamped againstthe cylindrical surface of the collar 22,'thereby maintaining the post 20 in rigid relation to the collar 22 and preventingtransverse movement thereof; 7

A forepart contacting member, shown as a toe rest 30 which is formed to'receive and center the forepart of, the shoe relatively thereto, is carried upon an arm 31 efztending laterally and upwardly from the jack post 32 which carries the heel pin or iron last. To provide means to permit lateral movement of the forepart contacting member, it

is mounted upon the supporting arm '81,

andmeans is provided foradjusting' the extent of the movements of the arm. The lower end of the arm'31 is provided with a sleeve 33, Fig. 8, which embraces a sleeve 34 having a shoulder 35 upon which the sleeve 33 rests. The sle'eveS is adjustably secured to the jack post 32 by means-ofa screw 36"passing through s n-r137 and threaded into an ear 38. The sleeve 33 is provided at with a V-shaped opening or notch, which embracesa pin carrieduby a.

slide ll which is mounted for vertical adjustment in the sleeve 34:. Upon the upper face of the sleeve 33 and freely engaging areduced portion of the sleeve 3% is an internally threaded collar l6, the threads of which engagethe threaded upper portionof the slide ie. Vertical movement of the collar 46 relatively to the sleeves33 and 3a is prevented by a washer 18 which is secured to the sleeve 34., a

It will now be clear that with the pin '42 in the position shown the sleeve 33 and arm 31 may have a certain amount of rotative movement relative to the sleeve 3% in either direction until the pin 425contacts with the sides of the notch 40 and it will also be ap parent that turning of the collar 46 will adjust the pin 42 vertically so that it may be made to contact with different vertical portions of the sides of the V-shaped notchso as to provide greater or less movement of the collar 33 relatively to the collar 34; and hence to permit greater or less swinging movement for the arm 31 carrying the toe rest. p a i I Referring now to Fig. 4, the vertically movable slide l l, which, as described, is operated from the treadle 6, carries upon its,

lower end a block 61 pivoted to the slide 14 at 62 and normally llGlCllll position with its lower facesubstantially horizontal by a spring (i l connected to a pin 65 on the block 61 and: a pin 66 upon the rearwardly eX- tending arm of the slide 14:. the line of the pins being normally above the axis 62 of the bloclr61. lhe presser plate support 68' is mounted upon the block 61 for longitudinal adjustment, by means of a headed stud on its upper side which engages a 'l way in the block shown at .63, Fig. 1, and by a clamping screw 70 by fwhich it is held clamped againstthe lower face of the block 61. The screw 70 passes through the threepoint clamp 72, through slot 73 in the rear portion of the supporting plate 68, and'is threaded into the block 61. The three-point clamp 72, instead of bearing against the sup port 68 at its forward end. bears against the presser' plate 76 which is thereby held clamped against the support. The presser plate 76 rests at its rear edge against pins 78 and has slots intermediate its ends engaging pins 79, the slots permitting a cerftainamount of lateral movement of the plate 70. It will be furtherlappar-ent that by suiiiciently loosening the screw 70 the plate 76 may be moved downwardly tofreeit from the pins 79 and may then be removed and replaced, the other side up, its curved V edge then assuming the position indicated in dotted lines in Fig. l. The platewill then serve for use with a knife having anoppoe site curvature to that employed with the plate when in the full line positionf The clamping plate may accordingly be adjusted longitudinally and laterally and omay be removed, reversed, replaced and again clamped in position by the manipulation of a single clamping screw.

In the use of the machine, a knife having a double curvature is secured in adjusted position in the usual manner bythe clamping nuts 51 in the knife carrier 52.7 The presser plate 76 havinga front edge with a curvature corresponding to thatof the knife is placed in position upon the'pins 78 and 7 9 under the clamp 72. It is then adjusted longitudinally and laterally until its edge is in parallelism with the contour of the rear side of the knife, and the clamping screw 70 breast" thereby changed without necessitat is tightened to hold the plate in adjusted position. Heels having a breast face of double curvature may now be breasted upon the machine, but will be identical in contour. To effect change of contour, the post 20 may be loosened upon the collar 22 and adjusted laterally to position the shoe-with itslong'i tudinal median line in different relation to thecurve of the knife and thecontour of the outline (in dotted lines) ofvztrious heels of a widely divergent contour are shown'as capable of being breasted upon a single knife by swinging the shoe about a vertical axis. 7

'Fig. '7 indicates diagrammatically how:

heels of differentsizes may be'given breasts I of similar appearance by swinging the shoe I heel.

and moving it slightly in the general direction of the longitudinal median line of the,-

V In this way the ratio of the length 'of one sicleof the heel to the lengthofithe other side'is kept the same irrespectivelyof the size of the heel, ,and'the proper length and width of the; portion of the heel oproj ecting'. under the instep arch is maintained.

P For purpose the lateral movement may ed by the knife.

for adjustment transversely: of the median be'combined with the swinging movement, if desired. After all the shoes of a certain kind, either rights or lefts, have been breasted it is necessary to'changethe knife to one of si'milar,but reverse, curvature. The necessity of providing a separate presser plate for the second knife is, however, obviated in the present invention by reversing the presser plate and clamping it in position the other side up.
